Muscles Worked
The biceps handles the primary load during this movement. The forearms assist as stabilizers throughout the range of motion.
How to Dumbbell Alternate Bicep Curl
- 1
Stand (torso upright) with a dumbbell in each hand held at arms length. The elbows should be close to the torso and the palms of your hand should be facing your thighs.
- 2
While holding the upper arm stationary, curl the right weight as you rotate the palm of the hands until they are facing forward. At this point continue contracting the biceps as you breathe out until your biceps is fully contracted and the dumbbells are at shoulder level. Hold the contracted position for a second as you squeeze the biceps. Tip: Only the forearms should move.
- 3
Slowly begin to bring the dumbbell back to the starting position as your breathe in. Tip: Remember to twist the palms back to the starting position (facing your thighs) as you come down.
- 4
Repeat the movement with the left hand. This equals one repetition.
- 5
Continue alternating in this manner for the recommended amount of repetitions.
Common Mistakes
- • Focus on the mind-muscle connection — feel the target muscle working through each rep.
- • Use a controlled tempo of 2 seconds up, 2 seconds down to eliminate momentum.
- • Start with your weaker side first — match the reps on your stronger side to prevent imbalances.
- • Squeeze at peak contraction for a full second — this is where most of the growth stimulus occurs.
